DSNMCom Messages
Cause. DSNMCom was unable to open the specified file.
Effect. If the error occurred on the input or output file, DSNMCom abnormally ends 
after writing a brief description of the error to the home terminal.
If the error occurred on the process file, the process file remains closed; any previously 
opened process file remains open.
Recovery. See the Guardian Procedure Errors and Messages Manual for a description 
of the specific file system or sequential I/O (SIO) error and the appropriate recovery 
action.
Cause. DSNMCom was unable to open the specified STARTUP parameter value in the 
$SYSTEM.SYSTEM.DSNM file (a section named env-name) during the DSNM 
initialization process because the specified section name is too long. The maximum 
acceptable length for env-name  (ZDSN-MAX-PARAMNAME) is 32 bytes.
Effect. A fatal error is reported, and DNSM is not started. 
Recovery. Correct and reissue the command. Refer to the Distributed Systems 
Management Solutions (DSMS) System Management Guide for information on DSNM 
process startup message parameters.
Cause. The command did not include an expected character.
Effect. DSNMCom is not started up.
Recovery. Correct and reissue the command. 
Cause. During the initialization of DSNM, inappropriate configuration input was 
submitted, or no configuration was submitted.
Effect. DSNM and DSNMCom cannot be started.
Recovery. Check your configuration files and try the DSNM initialization again. If the 
problem persists, contact your Tandem representative. Be prepared to describe the 
problem in detail as recommended in “What to Prepare Before Contacting Your Tandem 
Support Representative” on page B-1.
